I took the test yesterday and scored 750, and I owe a lot to this resource. It is not perfect, as many other reviewers have helpfully observed. Take the AWA stuff with a grain of salt; the best advice is found in actual ETS and GMAC materials, as well as the KAPLAN book. I liked the Quantitative section and the Joe Bloggs stuff throughout. Very clever. Be aware, however, that Princeton illustrations are ridiculously simplified; they make up examples problem to prove seemingly logical points. However, you will face many questions on the real GMAT that will stretch your math and verbal abilities.

Do all the practice tests you can -- in this resource, in the KAPLAN book, and in the 1400 questions available in three books from GMAC; in fact, time yourself on the paper practice questions with unrealistically low amounts of time. (I usually gave myself a minute per question to force myself to think quickly and select the best answer, even though the real GMAT gives you an average of about 2 minutes per question.)

I focused on sentence correction and data sufficiency for my study; I was fairly strong in reasoning, reading comp, and problem solving. The diagnostic tests and practice problems in these resources will help you determine what to focus on.

Buy this book, as well as the KAPLAN book and the three offered by GMAC. You will spend $150-$200 or so on all five books, but it is well worth it for a $250 test that you do not want to retake and that will figure quite heavily into the equation when you apply to top business schools.

This is book is not worth your time. The test strategy is so so.

The most problematic with this book is I found some errors in the quantitive sections (so far). There are times I cannot get the right answers ,and it turns out there are misprints.

I took the GMAT exam a few weeks ago. Initially, I used this book as the primary resource for test preperation. Everything seemed very easy until I picked up the ETS's sample questions/answers book. The questions in the Princeton Review are way too simple to be on the real GMAT exam. The questions on the GMAT exam are not "difficult", they're simply convoluted. There's a "gotcha" on about 80% of the questions on the GMAT. The GMAT really doesn't test your ability to learn or your command of the English language, and it simply likes to "trick" you into picking the wrong answers. Also, do not worry too much about the writing portion of the test. They're very straight forward, and if you can make an intelligent argument you will score high. The only piece of advise I can give you regarding this test to do good is practice, practice and practice. You really need to practice taking the real GMAT exams from the ETS' book. I did not take the exam seriously and spent very little time preparing for it. As a result, I did not get a very high score, but it was high enough for me to get into the school of my choice. Thanks to my high undergrad GPA. Good luck on the test.

I have used 3 different prep guides including a class. This is the worst CD ROM out there. I have only taken 3 of the practice exams, but with each one the software either froze up or scored one section before I had a chance to take the other. I would buy Kaplan and the Offical Guide instead.

I don't know if am going overboard, but I have 7 different books, 3 CDs, 4 websites, and PowerPrep software -- all from which I am culling information, pratice questions, and strategies from.

This book I am reading with great delight -- the concepts are easy to understand and the explanations in the answer section are clear.

A lot of people on this site are saying the practice tests in the Kaplan 2006 book are difficult, more difficult than the actual exam -- don't pay too much attention to that, since none of them are telling you exactly how well they did on the real test.

If they want to go to a regional, a 550 will get them in and for that circumstance, a 550 will suffice; the point is, everyone gets a different set of questions on their real GMAT and everyone has a different idea of what a "good score" is...

I also recommend the PowerPrep software, the Math Workout from Princeton Review, and the $1,300 dollar course given by kaplan at their test centers.

Dont' forget the Kaplan 2006 and 800 books -- you'll see that the questions are more difficult than those Princeton review gives you....

The book used in the 9 session course has hundreds of difficult practice problems -- you CANNOT buy this book online or find it anywhere else (even if you did, it'd do you no good since it is designed for classroom use).

Good luck.
